BUTTON OR STUD.

Specification of Letters Patent.

Patented May 28, 1907.

Application filed June 28, 1906. Serial No. 323,840.

To all whom it may concern.-

Be'it known that I, CHARLES E. HANsEN, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented a new and useful Improvement in Buttons or Studs,of which the following is a specification.

This invention has reference to an improvement in buttons or studs andmore particularly to an improvement in the means for detachably securinga button or stud to wearing apparel.

The object of my invention is to improve the construction of anon-separable button or stud whereby the button or stud is easilyinserted into different articles of wearing apparel and manipulated soas to be securely fastened or quickly removed from the same.

My invention consists in the peculiar and novel construction of a buttonor stud having details of construction, as will be more fully set forthhereinafter and claimed.

Figure l is a side view of my improved non-separable button or stud,showing the shoe in the closed position. Fig. 2 is a plan view of thestud or button looking at the under side with the shoe in the closedposition. Fig. 3 is an enlarged side view, showing the shank partly insection and the shoe in the closed position. Fig. 4 is a side viewsimilar to Fig. 3, showing the shoe in the open or extended position,and Fig. 5 is a detail face view of the shank showing the square hole inthe outer end of the shank for the shoe.

In the drawings, a indicates the head, I) the shank, and c the shoe ofmy improved button or stud. The head a may beof any material, design orconfiguration desired. The metal shank b is rectangular in cross sectionand has the square hole 6 extending transversely through the shankadjacent its outer end,a s shown in Figs 3 and 5, and is seouter end, asshown in Figs. 3 and 5, and is secured at its opposite end centrally tothe back of the head a by solder or other means. The shoe 0 is in theform of a split spring bar shaped in cross section to fit the squarehole 6 in the shank b, and is constructed to have the closed rounded end7, the inner and outer concavo-convex spring arms 8 and 9 merging intothe outwardly-curved hook-shaped ends 10 and 11 on which is a stop knob12. The inner spring arm 8 gradually increases in thickness from the end7 to the shank b to form the stop shoulder 13, and the outer spring arm9 gradually increases in thickness from the hook-shaped end 11 to theshank b to form the oppositely-disposed stop shoulder 14, the spacebetween the stop shoulders 13 and 14 being equal to the thickness of theshank b, as shown in Figs. 3 and 4. The shoe 0 may be formed integral orfrom flat spring wire bent as shown and the stop knob secured to theends 11 and 12 by solder. The spring arms 8 and 9 are slightly separatedwhen in their normal position by the spring tension of the arms and theconcave face of the arms are preferably toward the head a of the buttonor stud, as shown-in Figs. 1 and 3.

In the o eration of my improved button or stud the siioe c is held inits closed or transverse position by the stop shoulders 13 and 14engaging with the opposite sides of the shank at the edges of the hole 6in the shank through the tension of the spring arms 8 and 9, as shown inFig. 3. The shoe is opened or extended into a position to form acontinuation of the shank b by an inward pressure.

on the knob stop 12 or by pressing the sprin arm 9 between thehook-shaped end 11 anc the shank b toward the spring arm 8 to releasethe stop shoulder 14 and then pushing the shoe through the hole 6 in theshank until the stop knob 12 comes to a stop against the shank b, whenthe shoe assumes the position as shown in Fig. 4. The shoe 0 and shank bcan now be readily inserted through a button, stud, or similar hole inwearing apparel and the button or stud secured by pushing the shoe backin the reverse direction, when the stop shoulder 14 will automaticallysnap over the edge of the hole 6 in the shank and firmly hold the shoein the closed position.

I do not wish to confine myself to any one particular use as my improvedconstruction can be applied to collar buttons, shirt studs or any formof a button adapted to be detachably secured to wearing apparel.

Having thus described my invention, I claim as new and desire to secureby Letters Patent A button composed of a head, a shank having a holetransversely through its outer end, a shoe composed of two spacedconcavoconvex spring arms one overlyin the other In testimony whereof Ihave signed my and being connected to one anot er at each name to thisspecification in the presence of 10 of their endsaand being passe?throfugllli said two subscribing Witnesses.
